FRAME FOB TROLLEY HOISTS.

Application filed November 19, 1924. Serial No. 750,850.

T 0 all whom it may concern:

Be it known that I, SAMUEL E. KALBACII, a citizen of the United States, residing at Readmg, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Frames for Trolley Hoists, of which the following is a specification.

This invention relates to improvements in a combined hoist and trolley device, and the invention consists of a frame, formed in sections, and capable of being mounted upon a trolley to form, substantially, the body thereof, while at the same time the plurality of sections are so arranged as to provide housing and supporting means for the load carrying mechanism and the multiple gear assembly.

The invention consists of forming a hoist and gear frame in sections or units, so that three of said sections will provide the housing and supporting means for both the load carrying mechanism and the gears, the former being provided for by the middle section and one end section, while the latter is provided for by the middle and the other end section, the result being a compact and powerful device in proportion to its dimensions.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in which Figure 1 is a plan view of the entire trolley and hoist with the parts in position in the frame.

Figure 2 is an end view of the frame, as mounted on the trolley. Figure 3 is a detail view showing the three frame sections, slightly separated, and ready to be bolted together or assembled. Fig. 4 is an end view of one of the end sections of the frame.

The numeral 1 designates the ordinary trolley device for carrying the hoisting 'mechanism and gears. 2 designates the load carrying mechanism and 3 the multiple gears, all of which are of ordinary or usual construction.

The numerals 5, 6 and 7 designate the identical, in that each is formed with the lugs 9 for securing it to the centre section 6, which is formed with registering lugs for engagement withthe one end section 5 and with registering depressions 10 to receive the lugs 9 on the other end section, so that, when the three sections are brought together,

as clearly illustrated in Figure 8, and bolted together as shown in Figure 1, they will, assembled, form the body of the trolley; serve as ahousing and support for the gearing assembly; and also for a housing and support for the load carrying mechanism.

This frame, made up of three sections, arranged as above described, maybe applied to any trolley device of the general character illustrated. It will permit of an ease in handling that would not otherwise be obtainable, and the cost of construction is very materially lowered.

The present structure of frame, permits the elimination of a top suspension of the hoist, inasmuch as it is supported at the sides 0n the trolley frame, thus gaining head room.

In other words, this structure permits carrying the hoist within the trolley, instead of using the trolley merely as a suspension means for the hoist, thus making it applicable in many instances where an ordinary trolley hoist would not be sufficiently efiective.

l/Vhat I claim is 1. A frame for a combined hoist and trolley, comprising two like end sections, each of which is formed with perforated lugs, and a central section having lugs at one side adapted to register with the lugs on one end section and depressions at the opposite side adapted to register with the lugs on the other end section and bolts for securing the three sections together to form a frame. r 2. A frame adapted to house and support a load carrying mechanism and a multiple gear for actuating it, comprising three sections, each section having lugs formed thereon and means for securing the three sections together, whereby the load carrying mechanism is supported between one end section and the middle section, and the gearing between the other end section and'the middle section.

3. The combination of a hoist and a trolley on which it is mounted, with a frame formed with perforated lugs, and a central for supporting the load carrrying-anechasectionhaving-lugs inregister with the lugs nism and the gearing, said frame being on one end section ancll'iclepressibnsain regis- 10 made up of three sections formed with regis- .ter with the other end sections and bolts to Ii tering lugs and secured together by bolts. secure the three. sections together.

4. A three part frame for a. trolley hoist, In testimony. whereof I affix' 'my signature consisting of two likeend sections, each SAMUEL E. KALBAOH.
